Phytoestrogens (isoflavones & lignans)

Phytoestrogens are plant chemicals that display weak oestrogen-like properties in the body, but may have the effect of balancing high or low levels of oestrogen.  As such they may be beneficial for bone health, reducing menopausal symptoms and protecting against certain cancers.  They also exhibit cardio-protective properties

Isoflavones are a group of phytoestrogens found most commonly in soybeans and soybean products.  These phytoestrogens are also potent antioxidants.  

Lignans are a group of phytoestrogens found most commonly in seeds such as pumpkin, flax and sesame.  They also occur in rye, broccoli and some berries.  As well as their phytoestrogens properties, lignans are anti-inflammatory.
